New features

Added a -F flag which causes the supervisor process to
no longer fork down and detach and instead stay attached to
the tty. This allows integration with daemontools. PR#7628

Bugs fixed

The following bugs were found in Apache 1.3.24 and have been
fixed in Apache 1.3.26:

Allow child processes sufficient time for cleanups but making
ap_select in reclaim_child_processes more "resistant" to
signal interrupts. BZ#8176

In Darwin, place dynamically loaded
Apache extensions' public symbols into the global symbol
table. This allows dynamically loaded PHP extensions.

Fix for a problem in mod_rewrite which would lead to 400 Bad Request
responses for rewriting rules which resulted in a local path.
Note: This will also reject invalid requests as issued by
Netscape-4.x Roaming Profiles (on a DAV-enabled server)

Disallow anything but whitespace on the request line after the
HTTP/x.y protocol string to prevent arbitrary user input from
ending up in the access_log and error_log. Also control characters
are now escaped.

A large number of fixes in mod_proxy including: adding support
for dechunking chunked responses, correcting a timeout problem
which would force long or slow POST requests to close after 300
seconds PR#7552, adding "X-Forwarded" headers, dealing correctly with the
multiple-cookie header bug, ability to handle unexpected
100-continue responses sent during PUT or POST commands, and a
change to tighten up the Server header overwrite bug-fix.
